  • There have been studies reporting the increase in student confidence in mathematics when using technology. However, past studies indicating a positive correlation between technology and confidence in mathematics do not explain why they see this positive outcome. With increased availability and easy access to the Internet in schools and the development of free online virtual manipulatives, this research was interested in how the use of virtual manipulatives in mathematics can affect students confidence in their mathematical abilities. Our hypothesis was that the classes using virtual manipulatives which allows students to connecting dynamic visual image with abstract symbols will help students gain a deeper conceptual understanding of math concept thus increasing their confidence and ability in mathematics. The participants in this study were 46 fifth-grade students in three ability groups: one high, one middle and one low. During a two-week unit on fractions, students in three groups interacted with several virtual manipulative applets in a computer lab. Data sources in the project included a pre and posttest of students mathematics content knowledge, Confidence in Learning Mathematics Scale, field notes and student interviews, and classroom videotapes. Our aim was to find evidence for increased level of confidence in mathematics as students strengthened their understanding of fraction concepts. Results from the achievement score indicated an overall main effect showing significant improvement for all ability groups following the treatment and an increase in the confidence level from the preassessment of the Confidence in Learning Mathematics Scale in the middle and high ability groups. An interesting finding was that the confidence level for the low ability group students who had the highest confidence level in the beginning did not change much in the final confidence scale assessment. In the middle and high ability groups, the confidence level did increase according to the improvement of the contest posttest. Through interviews, students expressed how the virtual manipulatives assisted their understanding by verifying their answers as they worked and facilitated their ability to figure out math concept in their mind and visually.

  • The algorithm is a chain of mechanical procedures, capable of solving a problem. In modern mathematics educations, the teaching algorithm is performing an important role, even though contracted than in the past. The conspicuous characteristic of current elementary mathematics textbook's manner of manipulating multiplication algorithm is exceeding converge to 'standard algorithm.' But there are many algorithm other than standard algorithm in calculating multiplication, and this diversity is important with respect to didactical dimension. In this thesis, we have reconstructed the experimental learning and teaching plan of multiplication algorithm unit by making the best use of diversity of multiplication algorithm. It's core contents are as follows. Firstly, It handled various modified algorithms in addition to standard algorithm. Secondly, It did not order children to use standard algorithm exclusively, but encouraged children to select algorithm according to his interest. As stated above, we have performed teaching experiment which is ruled by new lesson design and analysed the effects of teaching experiment. Through this study, we obtained the following results and suggestions. Firstly, the experimental learning and teaching plan was effective on understanding of the place-value principle and the distributive law. The experimental group which was learned through various modified algorithm in addition to standard algorithm displayed higher degree of understanding than the control group. Secondly, as for computational ability, the experimental group did not show better achievement than the control group. It's cause is, in my guess, that we taught the children the various modified algorithm and allowed the children to select a algorithm by preference. The experimental group was more interested in diversity of algorithm and it's application itself than correct computation. Thirdly, the lattice method was not adopted in the majority of present mathematics school textbooks, but ranked high in the children's preference. I suggest that the mathematics school textbooks which will be developed henceforth should accept the lattice method.

  • This is a preliminary report on the first segment of a continuing and prospective teaming disorder study project in Korea. Study subjects were 197 children, aged between 6 and 15 referred for psychiatric evaluation of scholastic problems. Demographic data, psychiatric diagnoses and intelligence and achievement test results were reviewed and analyzed. Analyses of data lead to the following conclusions : (1) About 20.8% of children referred for scholastic problems were diagnosed of teaming disorder(LD). The most prevalent diagnosis among these children with scholastic problem was emotional disorder, especially depressive disorder(33%), (2) The comorbid rate of attention deficit/hyperactivity disorder(ADHD) of 41 children with LD was 44%, (3) Male/female ratio was 5.8:1 among all of the LD children, 17:1 among children with LD and ADHD and 3.6:l among children with LD but without ADHD, (4) 83% of children with LD scored above middle level on socioeconomic status(SES), (5) Age, SES, IQ, family psychiatric history, past history of medical and psychiatric illness, onset of age, pattern of peer relationship, number of friends, presence of adaptation problem and academic achievements of children with LD and ADHD compared to those of children with LD but without ADHD. No significant differences between two groups were found on age, SES, IQ, family psychiatric history, past history of medical and psychiatric illness, pattern of peer relationship, number of friends and presence of adaptation problem. However, there were significant differences in academic achievements of Korean language total, speaking and listening score, arithmetic score, social science score and music score of children with LD and ADHD compared to those of children with LD but without ADHD. Also there was an ealier onset of age in LD and ADHD group when compared to LD but without ADHD group.

  • In this study, we analyzed the influences of lecture design using CoRe upon the professor's teaching professionalism in the aspects of pedagogical content knowledge (PCK). The participants are three professors from the college of science-engineering located in Chungcheong-do. After collecting their syllabi, we observed their lecture and conducted the orientation. Afterward, we collected the CoRes which they prepared before the lecture. Then we observed their lecture and conducted semi-structured interviews. This process was carried out twice. We analyzed their syllabi, CoRes, videotaped lectures, field notes, the teaching materials, and interview transcripts. The results revealed that professors not only clarified the learning objectives and the characteristics of students but also reflected them in the lecture. In addition, they established the teaching strategies according to the characteristics of contents in the unit. As they recognized the necessity of understanding students' achievement, they selected the assessment method and applied it in the lecture. In some cases, however, they lacked presenting learning objectives specifically and explained students' misconceptions without inducing new concepts. They also presented a shortage of considering students' prior knowledge. They lacked providing students with an opportunity to participate in lectures, and their assessment method was not effective. Based on the results, we discussed implications to improve teaching professionalism using CoRe.

  • Some of the possible effects of revitalizing school libraries are improved personality education and an acquisition of the basic, as well as cultural, knowledge through expanded reading opportunities. The goal of school education is to increase the students' intellectual quality by providing structured education curriculums. In order to meet this goal, there has been increased interest in ways to enhance academic achievements or to increase the cognitive level of the students. In this study, we focused on the effects of school libraries on learning capabilities. To measure the learning capabilities, we used academic achievements as the evaluation criteria. Based on the statistical analysis, we found that the collection types and the reasons for using school libraries influenced the academic achievements more than the frequency of using school libraries. However, the influences of economic and social factors were too great in comparison to other factors. This paradoxically shows the importance of public education and the school libraries' role in education in general. In summary, school libraries should provide good quality reading experiences as well as methods to collect, manage, and use information to the students. These efforts will positively impact the academic achievements of the students.

  • School algebra starts with introducing algebraic expressions which have been one of the cognitive obstacles to the students in the transfer from arithmetic to algebra. In the recent studies on the teaching school algebra, algebraic thinking is getting much more attention together with algebraic expressions. In this paper, we examined the processes of the transfer from arithmetic to algebra and ways for teaching early algebra through algebraic thinking factors. Issues about algebraic thinking have continued since 1980's. But the theoretic foundations for algebraic thinking have not been founded in the previous studies. In this paper, we analyzed the algebraic thinking in school algebra from historico-genetic, epistemological, and symbolic-linguistic points of view, and identified algebraic thinking factors, i.e. the principle of permanence of formal laws, the concept of variable, quantitative reasoning, algebraic interpretation - constructing algebraic expressions, trans formational reasoning - changing algebraic expressions, operational senses - operating algebraic expressions, substitution, etc. We also identified these algebraic thinking factors through analyzing mathematics textbooks of elementary and middle school, and showed the middle school students' low achievement relating to these factors through the algebraic thinking ability test. Based upon these analyses, we argued that the readiness for algebra learning should be made through the processes including algebraic thinking factors in the elementary school and that the transfer from arithmetic to algebra should be accomplished naturally through the pre-algebra course. And we searched for alternative ways to improve algebra curriculums, emphasizing algebraic thinking factors. In summary, we identified the problems of school algebra relating to the transfer from arithmetic to algebra with the problem of teaching algebraic thinking and analyzed the algebraic thinking factors of school algebra, and searched for alternative ways for improving the transfer from arithmetic to algebra and the teaching of early algebra.

  • The effects of clarified mapping strategy and placement of analog on middle school students' conceptual understanding were investigated. According to the usage of clarified mapping strategy and the sequence in presenting analogy, four types of learning materials were developed and pilot tested. Prior to the treatment, the field dependence-independence test was administered and a previous achievement test scores were obtained. The scores were used as blocking variables. The learning materials were read by randomly assigned middle school students (N=111), and the conceptions test was administered immediately and four weeks later. In the recall problems of immediate and retention test, there were no significant differences. In the application problems of immediate and retention test, however, the students learned with clarified mapping strategy scored significantly higher than those with analog-only. Field-independent students learned with clarified mapping strategy scored significantly higher in the immediate application than those with analog-only, and higher-level students learned with clarified mapping strategy scored significantly higher in the retention application than those with analog-only. In the immediate application, higher-level students learned analog first with clarified mapping strategy scored significantly higher in the immediate application than those learned target concept first with clarified mapping strategy. However, lower-level students learned target concept first with clarified mapping strategy scored significantly higher than those learned analog first with clarified mapping strategy.
